The man who led Cricket Australia’s ball-tampering investigation that resulted in the suspensions of Steve Smith, David Warner and Cameron Bancroft has had his position suddenly terminated.

Iain Roy, Cricket Australia’s head of integrity and a member of the legal team for more than a decade, was told on Tuesday he was no longer required, according to The Australian.

It’s believed he received a redundancy payout and finished with Cricket Australia immediately.

Roy was dispatched to South Africa to head CA’s investigation into the events surrounding the ball tampering scandal in Cape Town in March, interviewing a number of players before recommending a 12-month ban for Smith and Warner, and a nine-month suspension for Bancroft.

His departure from CA comes amid claims from Al-Jazeera that two Australian players were involved in spot-fixing during the tour of India in 2017. CA said Roy's departure was by mutual consent and unrelated to the allegations raised by Al-Jazeera. CA also said it has no credible evidence of any such actions by Australian players.

According to The Australian, anti-corruption officer Sean Carroll will handle the match fixing allegations, which former Australian captain Ian Chappell says is the number one issue in cricket.

“I’ve always thought the biggest challenge facing the game is corruption,” Chappell told Wide World of Sports.
